Commuter traffic feeding onto the A40 adds a further, consistent contribution to local readings.

Light prevailing breezes usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Northallerton?
Most of spring and autumn stays fairly steady, right in the middle of those two extremes. There's a clear yearly cycle to air quality in Northallerton if you look closely. Once the heating goes on and the air turns still, pollution from the A40 and nearby chimneys tends to build up rather than clear. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days.
Are air quality levels in Northallerton based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
